Debian Security Advisory DSA-262-1                   security@debian.org

Package        : samba
Problem type   : remote exploit
Debian-specific: no
CVE ids        : CAN-2003-0085 CAN-2003-0086

Sebastian Krahmer of the SuSE security audit team found two problems
in samba, a popular SMB/CIFS implementation. The problems are:

* a buffer overflow in the SMB/CIFS packet fragment re-assembly code
  used by smbd.  Since smbd runs as root an attacker can use this to
  gain root access to a machine running smbd.

* the code to write reg files was vulnerable for a chown race which made
  it possible for a local user to overwrite system files

Both problems have been fixed in upstream version 2.2.8, and version
2.2.3a-12.1 of package for Debian GNU/Linux 3.0/woody.
